NBG4615 User’s Guide

The following table describes the labels in this screen. 

The QoS screen allows you to automatically give a service (such as VoIP and 
video) a priority level.

Table 47   Network > Wireless LAN > Advanced

RTS/CTS 
Threshold

Data with its frame size larger than this value will perform the RTS 
(Request To Send)/CTS (Clear To Send) handshake. 

Enter a value between 256 and 2432. 

Fragmentation 
Threshold

The threshold (number of bytes) for the fragmentation boundary for 
directed messages. It is the maximum data fragment size that can be 
sent. Enter an even number between 256 and 2346.

Output Power

Set the output power of the NBG4615 in this field. If there is a high 
density of APs in an area, decrease the output power of the NBG4615 to 
reduce interference with other APs. Select one of the following 100%, 
90%, 75%, 50%, 25% or 10%. See the product specifications for 
more information on your NBG4615’s output power.

HT (High Throughput) Physical Mode

 

- Use the fields below to configure the 802.11 

wireless environment of your NBG4615. 
Operating 
Mode

Choose this according to the wireless mode(s) used in your network.

Mixed - Select this if the wireless clients in your network use different 
wireless modes (for example, IEEE 802.11b/g and IEEE 802.1n modes)

Green - Select this if the wireless clients in your network uses only one 
type of wireless mode (for example, IEEEE 802.11 n only)

Channel 
Bandwidth

Select the channel bandwidth you want to use for your wireless network.

It is recommended that you select 20/40 (20/40 MHz). 

Select 20 MHz if you want to lessen radio interference with other 
wireless devices in your neighborhood.

Guard Interval Select Auto to increase data throughput. However, this may make data 

transfer more prone to errors.

Select Long to prioritize data integrity. This may be because your 
wireless network is busy and congested or the NBG4615 is located in an 
environment prone to radio interference.

Extension 
Channel

This is set to Auto by default. 

If you select 20/40 as your Channel Bandwidth, the extension 
channel enables the NBG4615 to get higher data throughput. This also 
lowers radio interference and traffic.
